Auditory Perceptual Development During Adolescence

描述(由申请者提供)：我的长期目标是了解青春期基本听觉任务表现发展变化的潜在机制。这个应用程序的当前目标是根据两个衡量个人表现的指标：平均表现和表现一致性，绘制青春期幼稚表现和训练诱导的学习模式的发展变化。本研究的具体目的是在(1)幼稚青少年和(2)受过训练的青少年中建立平均成绩的发展变化与成绩一致性之间的关系。为了实现这些目标，将收集青少年(11岁和14岁)和成年人(18-21岁)的平均表现和表现一致性的自然数据，并为这些听者中的一部分提供两项基本听觉任务中的每一项的多小时培训。拟议研究的结果将使我们能够更好地表征正常和无序的知觉发展，并导致创建更有效的知觉训练计划，以优化正常能力或治疗沟通障碍。

DESCRIPTION (provided by applicant): My long-term goal is to understand the mechanisms underlying developmental changes in performance on basic auditory tasks through adolescence. The current objective of this application is to map developmental changes in both naive performance and training-induced learning patterns during adolescence in terms of two measures of individual performance: average performance and performance consistency. The specific aims are to establish the relationship between developmental changes in average performance and performance consistency in (1) naive adolescents and (2) trained adolescents. These aims will be pursued by collecting na¿ve data on average performance and performance consistency from adolescents (11 and 14 years of age) and adults (18-21 years of age) and by providing multi-hour training to a subset of these listeners on each of two basic auditory tasks. The outcomes of the proposed studies will enable us to better characterize normal and disordered perceptual development and lead to the creation of more effective perceptual training programs for optimizing normal capacities or treating communication disorders.
